Git is powerful, but with great power comes the ability to really bork things up. When you find yourself looking at an inscrutable error message after an ill-advised late-night commit, it can be a maximum pucker-factor moment, and keeping a clear enough head to fix the problem can be challenging. …read more

It turns out that whacking busted things to fix them works as well on Mars as it does on Earth, as NASA managed to fix its wonky “mole” with a little help from the InSight lander’s robotic arm. Calling it “percussive maintenance” is perhaps a touch overwrought; as we explained …read more

Just a few weeks ago in the Links article, we ran a story about Tanner Electronics, the Dallas-area surplus store that was a mainstay of the hacker and maker scene in the area. At the time, Tanner’s owners were actively looking for a new, downsized space to move into, and …read more

A lot of annoying little hacks are needed to keep our integer-based calendar in sync with a floating-point universe, and the big one, leap day, passed us by this week. Aside from the ignominy of adding a day to what’s already the worst month of the year, leap day has …read more

Talk about buried treasure: archeologists in Germany have – literally – unearthed a pristine Soviet spy radio, buried for decades outside of Cologne. While searching for artifacts from a Roman empire settlement, the archeologists found a pit containing the Soviet R-394KM transceiver, built in 1987 and apparently buried shortly thereafter …read more

If you think your data rates suck, take pity on New Horizons. The space probe, which gave us lovely pictures of the hapless one-time planet Pluto after its 2015 flyby, continued to plunge and explore other, smaller objects in the Kuiper belt. In January of 2019, New Horizons zipped …read more

It’s been hard to miss these days, with reports of the red supergiant star suddenly dimming, and speculation growing that the star will go supernova sometime in the next 10,000 years.

In case you thought that we learned everything we need to know to land on the Moon fifty years ago, think again. NASA still has a lot of questions, and has scheduled the first of many commercial missions designed to fill in the blanks. As part of the Artemis program, …read more

Linux Fu: The Linux Shuffle

Computers are known to be precise and — usually — repeatable. That’s why it is so hard to get something that seems random out of them. Yet random things are great for games, encryption, and multimedia. Who wants the same order of a playlist or slide show every time?
